in reply to Perl Program Exits.
Are you running this on Windows, by double clicking a file icon? If I recall correctly Windows automatically closes the command-line window once the program has finished running when a program has been started this way, but there is a way to change that behaviour somewhere by right clicking the file and going into its properties.
